September 14 was Monarch Butterfly Day at Caesar Creek Lake. The U.S. Army Corps of Engineers was taking part in an international study tracking the 2000 mile migration of the butterflies back toward Mexico.
Citizen scientists were able to come out and search for butterflies in the wild in order to help capture them so they could be tagged for study.
The Army Corp of Engineer Ranger and other volunteers also released some Monarchs which they had helped raise into the wild.
Whether the butterfly is caught in the wild or raised by volunteers and released into the wild, an identifying tag is carefully placed on its wing.
Then the butterfly is released back into the wild.
When other citizen scientists anywhere in the world find or catch a tagged butterfly they can report the information on the tag which helps scientists track the butterfly’s migration pattern. Visit Monarch Watch Tags.
Because of changing farming practices in America, the Monarch Butterfly population has been on the decrease. Monarchs are dependent on the Milkweed plant for laying their eggs. This plant grew commonly at the edge of fields and along roadsides until recent times when farmers began pushing their fields to the very edge of the road and began aggressively eliminating weeds along the edges of the fields.
